Occlusal Splint Adjustment Protocol: What the Lab Wishes You Knew at Delivery

Most splint remakes that hit our bench in Mesa are not lab failures. They are delivery-day adjustment patterns that the prescribing dentist never got formally taught, because splint therapy gets maybe two lecture hours in most DDS programs and the rest is learned on patients. The Dobrikov bench has been finishing occlusal appliances since 1988 in Sofia and since 1993 in Arizona. Three generations of technicians, a lot of opinions, and a remake log that taught us where delivery goes sideways.

This is written for the general dentist or prosthodontist who delivers two to six splints a month and wants the appointment to run cleaner. If you are an oral surgeon prescribing a post-surgical stabilization splint, the same protocols apply, with the caveat that your patient's occlusion is probably still moving for six to twelve weeks and you will re-equilibrate.

1. Adjust the splint to the patient, not the patient to the splint

The single most common delivery error we see in the remake log is the clinician grinding the patient's natural dentition to make the splint fit cleanly, instead of adjusting the splint intaglio and occlusal surface to the arch as it presented that day. The splint is the disposable surface. The teeth are not.

If the splint rocks on insertion, the first move is pressure-indicator paste on the intaglio, not articulating paper on the occlusal. Identify the tight contact, relieve it with a fine acrylic bur, reseat, repeat. We mill our hard-acrylic splints with a 40 to 60 micron internal relief by default, but cases scanned with heavy retraction cord or scanned immediately after a hygiene appointment can still come in tight at one or two contact points. That is not a fit failure. That is a five-minute chairside adjustment.

If the splint will not seat at all, stop. Call the technician on the case. Every Dani case ships with the technician's direct line, and we will usually answer inside two hours during bench hours. A splint that genuinely will not seat is almost always a scan-capture issue at a specific tooth, and we can tell you which one from the CAD file in about ninety seconds.

2. Mark centric first, excursions second, and never at the same time

The second most common pattern in the remake log is articulating paper chaos. Two colors at once, patient tapping and sliding in the same breath, and a splint surface that looks like a Jackson Pollock by minute ten. You cannot adjust what you cannot read.

The sequence we recommend, and the one the prosthodontists who send us the highest-volume splint cases all use:

1. Seat the splint. Confirm full passive seating with finger pressure.
2. Thin blue articulating paper, centric only. Patient taps in their found centric, three to five times. Mark.
3. Adjust centric contacts to even, simultaneous, point-contact bilateral marks. We are aiming for the classic flat-plane goal: even posterior contacts, slight anterior clearance, canine or anterior guidance in excursion.
4. Wipe the splint. Switch to red thin paper. Patient excurses left, right, protrusive.
5. Adjust the excursive marks that cross the centric marks (the ones that will interfere), preserving the centric blue marks.

The key is the wipe between steps three and four. Skipping that step is how you end up with a splint that has no clear centric stops and a patient who comes back in two weeks reporting that the splint feels worse than no splint at all.

3. Anterior guidance is not optional on a flat-plane splint

We still receive prescriptions every month asking for a flat-plane splint with no anterior ramp and no canine rise. Usually this is because the prescribing dentist was taught that any guidance feature complicates fabrication. On a CAD/CAM workflow, it does not. Adding a shallow anterior ramp or canine guidance to a milled splint adds about four minutes to the design time and zero dollars to the case.

Why it matters at delivery: a truly flat splint with no excursive guidance lets the posterior teeth contact during lateral and protrusive movements. That is the opposite of what the splint is trying to accomplish for a bruxer or a TMD patient. The whole point is to disclude the posteriors during parafunction. If your flat-plane splint does not disclude in excursion, you are going to spend twenty minutes at delivery trying to grind in guidance that should have been designed in.

When you prescribe with us, the default on a flat-plane hard acrylic appliance is a shallow anterior ramp with canine-guided lateral excursions, designed off the patient's existing canine inclination from the scan. If you want something different, write it on the Rx. If you do not write anything, that is what you get.

4. The two-week recall is the appointment, not the delivery

The muscles relax. The condyles seat. The contacts change. Every splint we deliver is going to need at least one adjustment at the two-week mark and often a second at six weeks, and that is true regardless of which lab fabricated it. The key here is to bill for it up front. Patients who are told at delivery that the splint includes two follow-up adjustments at no additional charge come back. Patients who are not told that they need a follow-up do not come back, the splint stops fitting in the slow way that splints stop fitting, and six months later they are in a different practice telling someone the splint did not work.

For the small DSOs we work with across the southwest, this is the protocol question we get asked most often when a new location onboards: how do you standardize splint follow-up across fifteen offices when each dentist has their own habits? The answer that has worked: build the two-week and six-week recalls into the same treatment plan line item as the delivery, and the front desk schedules all three appointments on delivery day.

5. Call the bench before you remake

We stand behind every splint we ship. There is no charge for the call and no judgment for asking. The technician who finished the case knows that case better than anyone, including the dentist who delivered it, because the technician spent ninety minutes on the design and the dentist spent twenty minutes on the delivery.

That is the real foundation. The lab is part of the case, not a vendor at the end of it.
